James Baldassari commented on AVRO-996:
---------------------------------------
While investigating this issue I also found a couple of other bugs related to
the specific record builder, this time in the generated code:
* The build() method does not validate that all required (i.e. non-nullable)
fields have been set
* It's possible for build() to throw NPE when defaultValue(Field) returns null
and then the result of that call is set in a primitive field
I'm also going to include the fixes for the above issues in this patch, unless
anyone thinks it would be better to split them out into a separate issue/patch.
